Flange bearing for 5/8 in shafts

This Timken SCJT series flange bearing fits a 5/8 inch shaft and mounts with two bolts on a 3 inch center-to-center pattern. The cast iron housing holds a 52100 chrome steel ball bearing insert that locks by set screw. It is intended for general industrial and automotive machinery that needs a compact, relubricatable pillow block alternative.

Two-bolt mounting and set-screw locking

The 3/8 inch bolt size matches common drilled patterns, so the unit bolts directly to flat frames or brackets without adapters. Set-screw locking secures the inner ring to the shaft, eliminating the need for a separate locking collar or adapter sleeve. The one inch housing width keeps the assembly narrow where space along the shaft is limited.

Operating range and load ratings

Mobil Polyrex EM or an NLGI #2 equivalent grease is specified for relubrication across a temperature range of -65 to 200 degrees Fahrenheit. Dynamic load capacity is 2,360 lb and static capacity is 1,060 lb, suitable for moderate radial loads in conveyors, fans and light drives. The bearing is not designed for high-speed precision spindles or heavy shock-loading applications.

Questions about this item

What dynamic load capacity can the 5/8 in bore bearing sustain under continuous operation?

The bearing carries a dynamic load capacity of 2,360 lb and a static capacity of 1,060 lb, so sustained radial loads must stay within the dynamic rating.

How much heat can the cast-iron housing and Mobil Polyrex EM grease tolerate during all-day running?

The unit is rated for an operating temperature range of -65 to 200 degrees F, and the factory-fill Mobil Polyrex EM grease remains stable across that span.

Which shaft diameter and locking hardware must I already have to mount this SCJT flange unit?

You need a 5/8 in diameter shaft and a 3/8 in bolt for the two-bolt flange pattern; the insert uses a set-screw locking mechanism.
